Assuring a Sound Cycle of Water and Other Matter

Water Environment Department

In line with the Basic Environment Plan, the Water Environment Department is committed to help establish a socioeconomic system that minimizes the burden on the environment. The key objective is assuring a sound cycle of water and other matter in the environment.

Scheme of policy measures

Conservation of water environment
Protection of water guality (criteria: Environmental Quality Standard)

(1) Conservation of water quality in public waters
Regulations on effluent from factories and business establishments, and measures on
household effluent, etc. (Water Pollution Control Law)
  Special measures for lakes and reservoirs, enclosed sea areas, the Seto Inland Sea, and drinking water supply catchments
(2) Conservation of groundwater
Regulations on infiltration of pollutants from factories and business establishments into groundwater
  Orders to take measures to purify polluted groundwater
Assurance of a sound water cycle
Projects to recover and regenerate wells and springs
  Formulation of guidelines on standards to diagnose, evaluate and recover water cycle
Conservation of marine environment
Establishment of standards to regulate discharges of pollutants from ships and dumping of wastes into the sea (Law Relating to the Prevention of Marine Pollution and Maritime Disaster)
  Complying with international conventions relating to the marine environment, such as the United Nations Convention on the Law of the Sea
Measures on waste disposal and recycling
Establishment of standards on waste disposal and final landfill sites (Waste Management and Public Cleansing Law)
  Compulsory advance notification to importing parties and consent by them of export of specified hazardous wastes (Law for the Control of Export, Import and Others of Specified Hazardous Wastes and Other Wastes (Basel Law) )
  Study of a comprehensive system to promote desirable cycle of materials through an appropriate combination of waste disposal and recycing.
Conservation of soil environment (criteria: Soil Environmental Quality Standard)
Agricultural land: Designation of polluted areas, planning of countermeasures (Agricultural Land soil Pollution prevention Law))
  Urban area: Guidance based on guidelines for survey and countermeasures
Conservation of the ground environment
Regulations on extracting groundwater (Industrial Water Law, Law Concerning the Regulation of Pumping-up of Underground Water for Use in Buildings)
  Real time monitoring of groundwater levels, etc., distribution of information on the state of ground subsidence, and other reports
Prevention of environmental pollution from agricultural chemicals
Establishing standards for registration of agricultural chemicals, etc. (Agricultural Chemicats Regulation Law)

Selected 100 Exquisite and Well-conserved Waters
To encourage people through out the country to rediscover, utilize, and help conserve local sources of clean water, as has been done since ancient times in local communities, in March 1985 the Environment Agency announced a listing of the Selected IOO Exquisite and Well-conserved Waters, after assessing the water from springs and rivers all over the country.
Taking advantage of the listing, the cities, towns and villages where these selected waters are found have come together to establish the All Japan Water Environment Conservation Municipalities Liaison Council to promote and raise awareness of water quality conservation. The council organizes an annual All Japan Water Environment Conservation Muni-cipalities Symposium. The 1999 symposium is to be held in Nakamura City, Kochi Prefecture.

Selected 55 Beaches
In March 1998, the Environment Agency published a list of the "Selected 55 Beaches" scattering from Hokhaido in the nonh to Okinawa in the south, evaluated in terms of comfort, water quality and other features. The list has since been widely publicized.
One of the agency's motives in creating the list was to encourage more people to go to the named beaches in order to spark greater interest and involvement in water environment conservation. Another objective was to motivate local governments to work harder to improve their beaches so that they can makc the list in the next selection of Japan's "Selected 55 Bcaches "

Establishing an Environment-ally-sound Material Cycle
The practice of simply disposing of the waste is no longer adequate for dealing with our present waste problems. What is really needed is to construct a new society based on the desirable material cycle which can reduce the load on the environment at all stages of product life, from mining and harvesting of raw materials through to disposal.

Assuring a Sound Water Cycle
Natural cycles of water in the cnvironment have been disturbed as a result of problems such as drying up of springs and instability of river discharge, due to growing urbanization and other development. To restore water cycles to a sound state, it is necessary to take a comprehensive view of water systems, considering many different factors, including water quality and quantity. aquatic life, and the waterside.
